This year, Omega and Speedmaster fans everywhere are celebrating a milestone: the 60th anniversary of the Omega Speedmaster Professional. The Speedmaster, as the name implies, is a watch that began life as an automotive-oriented timepiece but went on to become much, much more: the watch worn by Gemini and Apollo crews and amazingly, in use to this very day in manned space flight.

We’ve partnered with Omega to bring you a four-part video series of Speedmaster collectors telling their own, personal stories about their Speedmasters, and what makes the model so uniquely fascinating. This is part two of four. Enjoy.
